SPRING PROTECTOR Filed March 9, 1936 Patented May 26, 1936 UNITED STATESPATENT OFFICE 4 Claims.

My invention relates to springs and has for its object to provide a newand eicient protector for screen door springs.

A further object is to provide a spring metal guard for coil springswhich guard has each end :engaged with the spring and is adapted to bendwith the spring to protect the spring and keep it from breaking where itbends around a sharp angle.

A still further object is to provide a door and spring protector whichwill protect both the spring from breaking or excessive stretching whereit engages the corner of the door, and which will also protect thecorner of the door from being marred b-y the bending of the springtherearound.

These objects I accomplish with the device illustrated in theaccompanying drawing in which similar numerals and letters of referenceindicate like parts throughout the several views and as described in thespecication forming a part of this application and pointed out in theappended claims.

In the drawing in which I have shown my device and its uses,

Figure 1 is a'plan view of the device shown attached to the door jam andto the door, parts cut away.

Figure 2 is a side elevation of Figure 1.

Figure 3 is a plan view of the spring protector.

Figure 4 is a face view of Figure 3.

Figure 5 is an end view of the one end of the guard or protector whichengages the end of the spring.

V Figure 6 is an end view of the end of the protector which engagesaround the spring.

Figure 7 is a plan view of the device showing the door opened.

Figure 8 is a view of a section of the spring showing a cylindricalslide in the end of the spring guard.

In the drawing I have shown the door jam as A, and the door as B. Thehinge is shown as C and suitable hooks or attaching devices are shown asD in the door jam and E in the door.

Into the door jam the hook D is screwed and the hook E is screwed intothe door a proper distance to give the correct amount of tension to around hole l2 therethrough, the end II to encircle the spring. The otherend I3 of the metal strip l0 is bent out at an angle and has preferablya square hole or rectangular hole I4 therethrough.4 This hole is to beattached over the loop 5 to hold the end of the metal strip I0 in properposition at all times for protecting the spring and for protecting thedoor.

Ihe end Il of the strip I0 may be provided with a cylindrical socket I6to slide over the spring as sho-wn in Fig. 8, so that the end of thestrip ID will never get caught in the coils of the spring S.

Figure 7 shows the use of the spring guard to hold the spring fromengaging against and `Inar- 15 ring the corner I1 of the door and toprevent spreading of the coils of the spring S thereby weakening thespring and stretching its coils so that they do not have any tension todraw the door closed.

This device may be used on and with any spring where it is to be exedaround or against an angled surface to protect the spring and also thesurface and any deviation or departure from the showing as set out inthe drawing and such 25 improvements as may be made do not depart fromthe spirit of the invention nor from the scope of the claims. l

Having thus described my invention I desire to secure by Letters Patentand claim: 30 1. In a spring for doors, the combination of a coilspring; means to secure the ends of the spring, one end to the door jamand the other end to the door; a flat door and spring guard carried onsaid spring with one end secured to 35 the end of the spring which issecured to the door jam and the other end slidably carried on saidspring.

2. In a closure spring to hold a closure in normally closed position,the combination of a coil 40 spring mounted on the closure and on theframe in which it is suspended; and a flat metal spring carried with theiiat side to engage the closure when it is opened, said spring to bendaround the edge of the closure when it is opened with 45 the curve ofthe coil spring.

3. In a closure spring, the combination of a coil spring; a flat metalguard for said coil spring mounted with one end to move on the exteriorof said spring and the other end to be secured to the end of the coilspring where it is secured to the frame in which the closure is tooperate.

4. A spring guard comprising, a flat strip of metal having the ends bentout at an angle to the body one end to be secured to the spring and theother end to be slidably carried on said spring, the entire guard tobend with said spring.
